To all whom t may concern:

Be it known that l, HAMILTON (l: BLUM- BERG, a citizen of the United States, residing at San Antonio, y in the county or" Bexar and State of Texas, have invented certain new and useful linprovements in Cylinder- Heads, of which the Jollowing is a specication.

. This invention relates to an improvement in removable cylinder heafls 'for engines which can he applied to number or cylinders, and the object is to provide integral intake and exhaust conduits. lllater is ceivecl within the heacl for n'iaintaining it in a cool condition, and the water is causefll to circulate around the intalre anti exhaust conduits and around the valve guides, so that all of the parts are maintained in a cool condition.

rIhe invention relates to still other novel features of construction and combinations of parts which will be hereinafter more fully described and vpointed out in the claims.

ln the accompanying drawings:

Figure 1 is a longitudinal vertical sectional View;

Fig. 2 is a transverse Vertical sectional View; and

Fig. 3 is a horizontal sectional View.

A represents the head, which is oreern ably made hollow for forming a water chamber through which the water may circulate for maintaining the head in a cool comliion. l have only shown the head as being applied to two cylinders, lout it is not the intention to limit the application of. the head to anyparticular number of cylinders. F or each engine cylinder, as is well known, there is an exhaust and intake port, and in this instance l have shown two exhausts and two intakes. The exhaust and intake conduits are cast integrally with the head., and the exhaust conduits are designated as l, and the intake conduits as 2. The exhaust conM duits are provided with a port which leafls from one side of the easing through the lower side thereof, as at 3, to the engine cylinder, through which the exhaust gases from the engine vcylinder are discharged. 'lhe in taire confiuits ll, e are located adjiacent to each other, and are so constructed that at their outer enel they converge into single conduit as at each coiuluit lleading to an engine cylinder, while the conduit 5 leads to the manifold, not shown.

Patenten @et semi no. asma tained, than by the usual four-'way method, generally provicletl The intake and exhaust ports, and particularly the exhaust ports 3, are 'formeel along the upper wall of the conduits l in an arc of say fortjwiive llegrees. The purpose of this is to prevent the exhaust `gases from carrying any ;gases, lubricating oil, carbon., or soot into the valve guides 6, which are connected to the conduits and head, and ein tend above the head il 'for forming a guifle for the Valve stems T, which carry the valves 8.

With the conduit or port generally pre .i'ifleil in gas engines, the exhaust gases will enter the guide along the valve stein, ancl eventually ca use the .st-eins to stick, but 'with the formation of the wall of the port at an angle of forty-five degrees at the point where the valve stein slides into the guide, it is possible to overcome this objection, and prevent direct inliux of the into the valve guides. The intake ports are provided 'with a valve 9, which have stems l0 connected thereto, sliding through guides ll., which are constructed similarly to the guide conduits and stein 'i' of the exhaust stein 7.0i the exhaust valves. These valves are seated against the. lower side of the lie-afl for forming a closure for the exhaust anti` intake ports., and are heldin this position by means oi' the springs l2, l).
